Asp.net MVC is really a great platform to build performant and very controllable web applications. But sometimes some functionality is scarcely documented if at all. Internet proves (thank you Google) to be an invaluable wealth of information in this regard since other developers are usually solving similar problems. But sometimes you either don't find usable information or you want to test things for yourself as well and learn something new as you go along.
Something similar happened to me on my previous project. I had to dynamically generate a list of objects in the browser and then reliably POST them back to web server so that data would be reliably model bound and validated as well. I wanted to avoid manual validation at all costs because it would unnecessarily overcomplicate server code.
